I skipped a version of Deramweaver and just upgraded to Dreamweaver 8 from Dreamweaver MX.
The box contains the Dreamweaver installation CD, and that is pretty much it. There is no printed documentation, no quick start guide, no registration form; everything is ether on the CD, or on the web.
You can install the Dreamweaver on a Windows computer or on a Mac, but not on both.
If a previous version is still installed, the Dreamweaver automatically locates it on first start and migrates the sites (at least when upgrading from MX this works very well), otherwise you need to enter the serial number of the Dreamweaver you are upgrading from. I find it useful to write down the previous serial number on the new CD envelope, so that I have it handy in case I need to reload Dreamweaver on a new computer in the future.
I really like that the Dreamweaver 8 seamlessly operates with different Doctypes and even allows converting from one Doctype to another. This is great when working with older web site designs for brining them up to date with modern standards. It can also validate markup and show you if there is anything in the document, or the entire site, that does not conform to the standards.
What's more, Dreamweaver can clean-up XHTML files, and HTML files created by Microsoft Word. The later command does not work very well, but Microsoft Word is known for creating a mess of HTML that is very difficult to deal with, so every little bit helps.
Besides markup validation, Dreamweaver can check such aspects of the web site documents as: Accessibility guidelines (including 508 and WCAG levels 1 and 2), browser compatibility, broken links, and XML validation.
This version of Dreamweaver includes great improvements in the area of CSS design. CSS rules and properties are now easy to browse, and the layout view is very nice. Unfortunately, many design elements in Dreamweaver are still table based, for example, most of the built-in snippets use tables for layout instead of CSS.
The design view now can be zoomed in or out for precise positioning of elements. Vertical and horizontal guidelines can be dropped to help with element orientation.
The code editor is also improved; one of the nice new features is code folding, where blocks of text can be hidden for cleaner view.
Many agree that Dreamweaver is the best web design tool available, and I think that Dreamweaver 8 is a worthy upgrade. I highly recommend it.
